Experts Say Aztec Emperor's Tomb May Be Under Monolith

Mexican archeologists say they have found signs that the tomb of an Aztec emperor could lie beneath a recently excavated stone monolith showing a fearsome, blood-drinking god.

It would be the first burial site ever found of a leader of the 1427-1521 Aztec empire, said archaeologist Eduardo Matos, who leads the excavation project at the Templo Mayor ruins around Mexico City's main square.

"We think this could be a gravestone covering the place where this ruler was laid to rest," Matos said Thursday, as he showed reporters the carved face of the stone for the first time since it was discovered Oct.2.
